## FAQ

### How much does it cost to build an app like WhatsApp?
On a messaging base we've already proven, a WhatsApp-style MVP — 1:1 and group chat, media, presence — typically starts in the lower five figures. Voice and video calling plus end-to-end encryption add to that. Send your requirements for a free quote.

### How long does it take to build a WhatsApp clone?
A branded messaging MVP on the tailored foundation generally takes 8-12 weeks. A full app — group video calls, encryption, multi-device sync — needs 3-5 months, run as agile sprints with demos every two weeks.

### Is the messaging really end-to-end encrypted?
It is. Messages and media are end-to-end encrypted, so only sender and recipient can read them. Disappearing messages, secure backups and configurable data retention are all available on top.

### Does it support voice and video calls?
Yes — one-to-one and group voice and video over WebRTC, with dependable signalling, presence, and push notifications covering reconnections and missed calls.

### Do I own the source code?
Yes. The source code and infrastructure are entirely yours, no vendor lock-in, with optional ongoing maintenance and support if you'd like it.
